I don't very like this that much because you can't really say what is the most used redstone circuit is because some people don't use it and redstone is something that is completely optional in the game it would be more of a redstone noob.

A lot of these questions are actually pretty amatuer themselves... I should do my own test.

For one, staircase mining isn't the best way to mine. I actually mine straight down but I stand between 2 blocks and that allows me to mine straight down while at the same time standing on another block to avoid falling into a potential ravine, cave, or pool of lava. Make a water drop and a ladder and that's the quickest way. From there you branch mine.

The best materials aren't just found a couple blocks above bedrock, they are actually up to 16 blocks above bedrock which is pretty far.

How do you expect me to remember exactly how many mobs I have killed, and exactly how many hours I have played Minecraft? Also, just because I started playing Minecraft last summer, not in the Alpha days, why exactly would that make me a noob?

The test was alright but there should be more questions to more technical stuff and some of the questions conflict on how the way some people like to play. The test assumes that if you play on peaceful you are an automatic noob.
